2. Check that the fiber terminators are clean. You can clean the cable plugs by
wiping them gently with a clean tissue or cotton ball moistened with a little
ethanol. Dirty fiber terminators on fiber cables will impair the quality of the light
transmitted through the cable and lead to degraded performance on the port.
3. Connect one end of the cable to the LC port on the switch and the other end to
the LC port on the other device. Since LC connectors are keyed, the cable can
be attached in only one orientation.

4. As a connection is made, check the Link LED on the switch corresponding to
the port to be sure that the connection is valid.
The 1000BASE-SX, 1000BASE-LX and 1000BASE-LH fiber optic ports operate at
1 Gbps full duplex. The maximum length for fiber optic cable operating at Gigabit
speed will depend on the fiber type as listed under “1000 Mbps Gigabit Ethernet
Collision Domain” on page 4-7.
10 Gbps Fiber Optic Connections
An optional 10GBASE transceiver (Xenpak) can be used for a backbone connection
between switches.
Each multimode fiber optic port requires 50/125 or 62.5/125 micron multimode fiber
optic cabling with an SC connector at both ends. Each single-mode fiber port
requires 9/125 micron single-mode fiber optic cable with an SC connector at both
ends.
Warning: This switch uses lasers to transmit signals over fiber optic cable. The lasers are
compliant with the requirements of a Class 1 Laser Product and are inherently
eye safe in normal operation. However, you should never look directly at a
transmit port when it is powered on.
